ABSTRACT:
A liquid dispensing device for chemical titration having a reciprocating plunger for expelling fluid from an attached titrating solution cartridge, and a lead screw for reciprocating the plunger whose rotation is measured and displayed by a digital rotation counter. The plunger can be selectively uncoupled from the lead screw to permit direct plunger positioning. A pair of manual knobs allow rapid direct rotation of the lead screw or slower, geared down rotation of the screw.
